PAUL CANCIENNE, OF IBELLEIROSE, LOUISIANA.

IP'B'OGRAM CLOCK.

Application filed April 28,

To all whom it may concern.

Be it known that I, PAUL CANCIENNE, a citizen of the United States, residing at Bellerose, in the Parish of Assumption and State of Louisiana, have invented new and useful Improvements in Program Clocks, of

' closed selectively upon the passage of the clock hands across its face.

An additional object is'the provision of a relay switch device for controlling the closing of independent circuits having the signal hells or other signal devices therein.

The invention further contemplates the general improvement of devices of this class in details of arrangement and construction which will make for simplicity, cheapness in manufacture, ease of adjustment, efliciency and durability.

Vith the above and other objects and advantages in view the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which: 1

Figure 1 is'an elevation of a clock embodying my invention,

{Figure 2'isa section on the line 2-2 of Figure 1,

Figure 3 Figurel,

Figure 4 is a diagram of the circuits.

Referring more particularly to the draw ings the letter A designates a clock having the usual face B over which travel the hour and minute hands C and D respectively.

In carrying out the invention I provide a ring 10 of suitable insulating material is a section on the line 33 of mounted on the clock face outwardly of the dial and carrying a metallic ring 11 preferably formed with a flange 12- embedded within the ring 10. At fi've minute intervals the ring ll is formed with contact lugs 13 1924. Serial No. 709,599.

which overlie the ring 10 for engagement by an elongated contact finger 14 carried by the minute hand D.

Located on the dial and secured thereto in any desired manner in spaced relation to and inwardly of the ring 10 is aring 15 of insulating material equipped at its sides with metallic rings 16 and 17 each of which has a flange 18 embedded within the ring 15 so as to be securely anchored. Inwardly of this ring 15 the dial has a series of graduations 19 thereon opposite which are inscribed indicia 20 indicating diflerent times and these graduations and indicia'mustcorrespond with the actual time. Necessarily the hands 0 and D are accurately disposed so that when the hourhand points to any certain hour, the minute hand must be at the very top, no laggingor advancing between the two hands being permissible as otherwise the device would not function properly.

In connection with the rin assembly formed by the parts 15, 16 and 1 I provide a series of similar clips 21 which are of substantially U-shape with one leg shorter than the other and which are adapted to be engaged upon this ring assembly opposite any graduation 19 and indicia 20 at the time when it is desired to give the signal. These clips are reversible and are consequently capable of engagement upon the ring assembly in such a way as to engage either the ring 16 or the ring 17, the alternative arrangements being clearly indicated in Figures 2 and 3. These clips 21 are in the path of movement of a contact finger 22 carriedby the hour hand O.

The electrical connections may of course be varied depending upon the exact nature of the signals to be controlled and the character of the current employed. However,

in Figure 4 I have shown two different program bells 23 and 24 and' have also illustrated a switch device indicated at S. This switch device includesan armature 25 movably mounted between a pair of electromagnets 26 and 27 and carrying a contact:- 28 adapted to engage either of a pair of contacts 29 and 30. One terminal of the bell 23 is connected bya'wire 31 with one terminal ofa suitable source of current 32 which has its other terminal connected by a wire 33- with the armature 25. The bell 23 has the above mentioned terminal connected by a wire 34 with one terminal of the bell 24 while its remaining terminal is connected by a wire 35 with the contact 29. The other terminal of the bell 24 is connected by a wire 36 with the contact 30. The numeral 37 represents a separate source of current which is connected with the metallic ring 11 by any desired means. The other terminal of this source of current 37 is connected by a wire 38 with one terminal of each of the windings of .the electromagnets 26 and 27. The remaining terminal of the magnet coil 26 is connected with the metallic ring 17 while the remaining terminal of the magnet coil 27 is connected with the metallic ring 16.

In the operation, it will be seen that a plurality of the clips 21 should be engaged upon the ring 15 at the points opposite the exact times at which it is desired to ring the bells. The clips for controlling the circuit for ringing the bell 23 must be so arranged onthe strip 15 as to engage the metallic ring 17, while the clips for controlling energization of the bell 24 are reversed so that they will engage the metallic ring'16. As the minute hand moves during the operation of the clock its finger 14 will pass over the successive lugs 13 and when it engages any lug 13 which corresponds to the clip 21 set at a certain time period it is evident that the current from the source 37 flowing through the ring 11 will pass through the contact finger 14, hand D, hand G, finger 22, contact 21, and either to the coil 26 or 27 as the case may be depending upon the position of the clip 21 engaged. If the clip 21 engaged at this time is sopositioned that it touches the ring 17, current will flow through the magnet coil 26 back to the source 27, resulting in energization of the magnet and attraction of the armature so that the contact 28 carried thereby will engage the contact 29. When this occurs, the current from the source 32-will pass through the wire 33, armature 25, contact 28, contact 29, wire 35, and through the bell back throu h the wire 31 to the source, thus soundlng the bell. If the clip engaged at this time should be touching the ring 16, it will be the magnet 27 which is energized in the same manner and this magnet will attractthe armature so that the contact 28 will engage the contact 30 and close the circuit through the bell 24. As many clips as desired may be engaged on the ring 15 and reversed with respect to eachother as may be necessary for controlling the two programs and there is of course no restriction in this respect.

The relay switch device S is intended for use when a heavy current is employed and might be omitted if desired, the connections being then made directly.

From the foregoing description and a study of the drawings it will be apparent that I have thus provided an extremely simple and inexpensive program clock device which is capable of use in factories, work shops, schools and other places of learning, or in fact anywhere else where it is desirable to give signals for distinguishing between or marking ofl' different periods.

While I have shown and described the preferred embodiment of my invention it is of course to be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invenof the dial, a finger on the minute.

thereby, and clips engageable upon said insulating ring in the path of the hour hand, said clips being of U-shape and having one leg longer than the other whereby the clips may bedisposed selectively with the long leg touching a selected one of the metallic rings and the short leg out of engagement with the other metallic ring.

2. In combination with a clock having hour and minute hands movable over a dial, a series of contacts arranged circumferentially of the dial, a finger on the mnutc hand traveling over the successive contacts, a ring of insulating material mounted on the clock 'dial inwardly of said contacts, separate metallic rings located at opposite sides of the insulating ring and carried thereby, and clips engageable upon sad insulating ring in the path of the hour hand, said clips being of'U-shape and having one leg longer than the other whereby the clips may be disposed selectively with the long leg touching a selected one of the llutillllr' rings and the short leg out of engagement with the other metallic ring, an electromagnetic switch device connected in circuit with a source of current and said contacts and metallic rings, the switch device including a movable contact and separate contacts adapted to be engaged thereby. and signal devices connected in circuit with said last named'contacts and a local source of cmrent.

In testimony whereof 'I affix my signature.

PAUL OANOIENNE.
